There are several reasons for insomnia that not everyone considers when they are lying awake at night wishing they could get some sleep. The reasons people have insomnia vary based on many different factors. The good news is: whatever causes insomnia it can be treated. When people use the term insomnia it can mean several different things, all of them having to do with not getting restful sleep. Insomnia can be difficulty falling asleep, trouble staying asleep (waking up in the middle of the night), trouble falling back asleep after waking in the night, or waking up early in the morning. All of these types of insomnia can lead to lethargy and tiredness the next day. Suffering from insomnia for extended periods of time can lead to a lower quality of life and even higher mortality rates if your sleep per night is less than 4.5 hours on average.

Common reasons for insomnia

Some of the reasons for insomnia are very common, and sometimes very easy to avoid. One of the most common causes of insomnia is the environment in which you are trying to go to sleep. Simple reasons like noise, uncomfortable bedding, sleeping in a new place, too much light, and airborne allergens can all cause difficulty sleeping. This is often referred to as "sleep hygiene". Poor sleep hygiene is a one of the most treatable reasons for insomnia. You have quite a bit of control over the environment that you sleep in. Try closing the shades before you go to bed. Leave the television off when you are trying to get to sleep. Think about putting in a pair of earplugs or trying on a sleep mask. Change your sheets regularly to get a more comfortable feeling bed. There are countless things you can do to improve your chances for a quality night of sleep. Every person has their own set of conditions that will be most conducive to a quality nights sleep – don't be afraid to experiment a little bit with your environment.

Another very common reason for insomnia is the things you put into your body. We all know that a cup of coffee helps us get the day started, so it should come as no surprise that excess caffeine can play a large role in insomnia. All stimulants such as caffeine, taurine, cocaine, amphetamines, ephedrine and many others will have a profound effect on your ability to sleep. This makes intuitive sense as these drugs all have the effect of speeding up the body, exactly the opposite condition that will help avoid insomnia. Using anti depressants is one of the least intuitive reasons for insomnia. While stimulants make perfect sense, you may have to check with your doctor about the anti depressants you are taking as they may be playing a significant part in your insomnia troubles.
